Re: [GnomeMeeting-list] Unexplained Error

[George <geboyd netzero net>]

This is the last part of strace where it failed. I changed the
permission on /dev/video back to what it was when I got the error
before.


lstat64("/dev/video", {st_mode=S_IFDIR|0666, st_size=4096, ...}) = 0
open("/dev/video/", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 17
fstat64(17, {st_mode=S_IFDIR|0666, st_size=4096, ...}) = 0
fcntl64(17, F_SETFD, FD_CLOEXEC)        = 0
gettimeofday({1047598029, 657694}, NULL) = 0
gettimeofday({1047598029, 657711}, NULL) = 0
gettimeofday({1047598029, 657727}, NULL) = 0
getdents64(0x11, 0x81406d8, 0x1000, 0x81406a8) = 176
lstat64("/dev/video/em8300_ma", 0xbffff100) = -1 EACCES (Permission
denied)
fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x40059000
write(1, "Operating System error\n", 23Operating System error
) = 23
write(2, "Catastrophic failure, PProcess::"..., 51Catastrophic failure,
PProcess::Current() = NULL!!
) = 51
_exit(1)                                = ?
